# Smash factor by club

Smash factor is ball speed divided by club head speed, and loft caps it: the tour driver runs 1.48, the 7 iron 1.33 and the pitching wedge 1.23 on the published table. The model eases each club by 0.01 for every 5 mph below its tour speed, and 0.01 of smash is worth about 1.9 yards with a driver at tour speed.

## Key figures

- Tour smash factor runs from 1.48 with a driver to 1.23 with a pitching wedge.
- One hundredth of smash factor is worth about 1.9 yards with a driver at tour speed.

## Scope

- Tour values are the published ball speed and club head speed rows; the slower columns apply the model’s stated easing of 0.01 per 5 mph below tour speed.
